Questions

Can I use my real handwritten signature?

Yes. Take a photo of it on white paper; pdfSofo removes the paper and keeps only the ink.

Where is my signature stored?

Only in your browser, on your device. You can delete it any time.

Do I need an account?

No account, no email, no sign-up. Open the page and start.
